Sony has released its Authoring Tools Framework as a free open-source download on GitHub.

The toolset has been used in the development of titles such as The Last of Us and Beyond: Two Souls. The development tool supports PS4, Vita, PS3 and PSP games.

The framework is written in C# and features a set of software components for making tools on Windows.

"We’re looking forward to expanding ATF’s usage beyond SCE, working more with external PlayStation developers and the larger game development community as a whole," said SCEA principal tools programmer Ron Little.

“Now that ATF is open-source, we’re excited to see the ways developers use the toolset, which could expand beyond games.”

More information about the Authoring Tools Framework will be discussed at GDC on March 19th between 3:30pm and 4:30pm in room 3020 in the West Hall.
